My wife is pushing for one of these very expensive home water treatment/filtration systems, but it all feels like a scam to me. No one I know has one, so turning to random strangers on the internet for opinions.
Edit: We’re on city water in a decent area. No well water. It’s more about removing the chlorine and microplastics than anything.
Check whether your water has been treated with chlorine or chloramines, which are more common these days.
